Vagus Nerve Stimulation for Cluster Headache
Does vagus nerve stimulation help with cluster headache? 20 human studies have investigated VNS for cluster headache, including 4 systematic reviews, 6 RCTs, and 3 observational studies, published between 2007 and 2025, with 7 published since 2022. Studies use transcutaneous cervical (tcVNS), implanted (iVNS), and transcutaneous auricular (taVNS) stimulation. Findings vary by study design and population; the studies below are ranked by evidence strength so you can weigh the research directly.
